Ahh... I did update the chipset drivers instead of using microsoft's. I guess I may have to uninstall them and hope that it's not a hardware limitation. I did check to see if trim is working through the command line. It does seem to be on. ACHI is enabled in the bios too. Two other hard drives and a dvd drive is connected to all 4 of my sata ports.

I was using HD tune to get the average values. Here are my results for the other benchmarks.

the s510 has some pretty low end flash on it i bought 2 and returned them the next day they are not very fast at all for sandforce 2281 controller because of the flash hence why adata launched the s511 right after those read and writes where the same i got on a z68 chipset there about as fast as the old indilinx ssd
